So what happens when he awakens one day to a talking lizard, who informs him that there is a gigantic hammer in outer space that is poised to split Earth into pieces? In the adventure of a lifetime, Yuuhi will join forces with a super-powered princess and a motley crew of companions. Their mission: defeat an evil mage and his horrifying homunculus before the Biscuit Hammer can destroy the planet!"--Cover, p. [4].
